Objectives: We sought to determine whether the endoscopies that met the Sydney protocol in a population of Antioquia had a greater detection of H. pylori and their associated lesions than the endoscopies that only took antrum samples. Materials and methods: We carried out a retrospective, cross-sectional and descriptive study. Adult patients undergoing upper endoscopy were included. Patients were divided into two groups depending on Sydney protocol compliance. The detection frequency was measured for H. pylori and premalignant lesions. Results: 261 participants were included, 88 from which biopsies were taken with the Sydney protocol and 173 with biopsies taken exclusively from the gastric antrum. The main endoscopy indication was dyspepsia (35.6%). The detection of H. pylori, atrophic gastritis and intestinal metaplasia was 36.4%, 19.3% and 20.5% respectively in the Sydney group, and 30.1%, 11.6% and 9.8% in the control group. In the Sydney group, the detection of H. pylori was higher in the antrum and body (26.1%) than in antrum (6.8%) or body (3.4%) separately. The detection of atrophic gastritis and intestinal metaplasia was higher in antrum only (10.2% and 11.4% respectively) than in antrum and body or body separately. Conclusions: The omission of the Sydney protocol reduces the detection of H. pylori, atrophic gastritis and intestinal metaplasia by 9.4%, 29.4% and 27.7% respectively. The protocol must be implemented systematically in every gastrointestinal endoscopy center.
